  • Sub-viewController doesn't get autorotation notifications, bug?

    - by Shizam
    If I have a view (and its controller) and I override the willAnimateRotationToInterfaceOrientation method so I can respond to autorotation events everything works fine and dandy. Now if I create another viewController and add its view to the first viewController's view via: [firstViewController.view addSubview:secondViewController.view] The secondViewController's willAnimateRotationToInterfaceOrientation method isn't called. What gives? Thanks, Sam

  • Is it possible to create a UINavigationController within a ModalPopup?

    - by aloo
    Hi I have a modalViewController that I am popping up using [self presentModalViewController:myController animated:YES]; I have an event occurring within myController which I would like to result in another controller being pushed onto the navigation stack ON TOP OF myController (which again has been presented modally). How can I do this? I have tried the following from within myController: UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:self]; NewController* n = [[NewController alloc] init]; [navController pushViewController:n animated:YES]; [n release]; This does not work however....

  • Create facebook object each and every time?

    - by oshirowanen
    I have a login page which will log a user into my webapp based on their facebook login details. I then create a session to remember who they are. What I want to know is, should I be creating and/or checking the facebook credential on every single page of my webapp, or should I simply use the session I create at the beginning to login? For example, once they have logged in, I would like to allow them to post a message onto their own facebook wall from my app. Should I check the login credentials before they can post by recreating the facebook object, or should I simply use the stored login details already in my session and use that to post to their facebook wall?

  • Will it use more and more memory if I keep drawing on the UIView?

    - by Tattat
    This is my drawRect: CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(context, 2.0); CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor); CGContextMoveToPoint(context, x1, y1); CGContextAddLineToPoint(context, x2, y2); CGContextStrokePath(context); If I run this code thousand times or more. My UIView will have many lines on that. Will it use more memory than only just one line on it? Er... ...I mean, will the program remember the line I draw or after it draw the lines, it won't have any information in the memory. thz .

  • How to cancel a touch sequence

    - by Alex
    I have an UIImage view that responds to touch events. I want to cancel the touch sequence if the touch goes outside of certain bounds. How can I do that? I know that I can inspect the coordinates of the touch object, what I don't know is how to cancel the sequence. I don't see any event in the API that allows for that.

  • Does iOS 4 Have "Real" Multitasking?

    - by pkulak
    Ever since the first beta came out I've been trying to find out if "real" multitasking is possible. I.E., can you put a program in the background and have it hang on to a network connection indefinitely? I'm thinking about IM or IRC apps, for example. I've compiled an app myself on OS 4, and without changing a thing it appeared to stay running in the background, but for all I know it was just suspended to memory. The docs say the best you can do is request up to 10 minutes, but in the developer presentation they showed off Skype sitting in the background and then notifying the user that a call was coming in. Does anyone know for sure how this is all going to work?

  • NSMutableArray in appdelegate - EXEC_BAD_ACCESS

    - by Tejaswi Yerukalapudi
    Hi, I'm trying to use a global array in the appdelegate as a quick fix for a demo I'm building. The relevant code for this .h file has the declaration { NSMutableArray *trnEntered; } @property (nonatomic, retain) NSMutableArray *trnEntered .m file has the following code - trnEntered = [[NSMutableArray alloc] init]; NSLog(@"%@",[trnEntered count]); // prints null. [trnEntered addObject:@"1"]; NSLog(@"%@",[trnEntered count]); // exec bad access. Not sure where I'm going wrong here. Looks fairly straight forward. Thanks for the help in advance, Teja.
